compiling cocoa lumberjack with Xcode 8.3.2 results in errors in DDOSLogger.m


Trying to build cocoa lumberjack/swift via cocoa pods. Compiling the latest tag 3.2.0 ends up with errors in DDOSLogger.m Here a sample:

I've updated cocoa pods, tried this with the last Xcode 8.3.1, cleaned everything, etc... no luck. What surprises me is that I can't find any discussion of this... apparently I didn't get the message because everyone else either has this working or is using an older tag.

Using tag 3.1.0 works fine, I believe among other things it doesn't have the DDOSLogger included.


Solution

  • I'm not sure if you've managed to fix this, but a similar issue is described here - https://github.com/CocoaLumberjack/CocoaLumberjack/issues/883

    Essentially it was a bug in the CocoaLumberjack that appeared with new version of Xcode and it has already been fixed.
